Simple-Calculator-With-Python

This is a basic calculator implemented in Python using the Tkinter library.

How to Use

  1. Run the script (calculator.py).
  2. The calculator window will appear, displaying an entry widget at the top for input and output.
  3. Use the numeric buttons (0-9) and arithmetic operators (+, -, *, /) to input your expression.
  4. Press the "=" button to calculate the result.
  5. Press the "C" button to clear the entry.
  6. If there's an error in the input expression, "Error" will be displayed.

Code Structure

  • on_click(value): Appends the clicked button's value to the current input in the entry widget.
  • clear_entry(): Clears the entry widget.
  • calculate(): Evaluates the expression in the entry widget and displays the result. Handles errors gracefully.

Buttons

The calculator has the following buttons:

  • Digits: 0-9
  • Arithmetic Operators: +, -, *, /
  • Other: . (decimal point), = (equals), C (clear)

Dependencies

  • Python 3.x
  • Tkinter (included in most Python installations)

Running the Code

Make sure you have Python installed on your system. Then, run the script using the following command:

python calculator.py

Notes

  • This calculator supports basic arithmetic operations.
  • The code uses the eval() function to evaluate expressions, so avoid using it with untrusted input.
  • Feel free to modify and enhance the code according to your needs!
